REED-SUPPORTING DEVICE FOR LOOMS.

SPECIFICATION forming part of Letters Patent No. 499,870, dated June 20,1893. Application filed February 16, 1893- Serial No. 462,574. (Nomodel.)

To all whom, it may concern.-

Be it known that I, JOSEPH W. CHENEY, a citizen of the United States,residing at Three Rivers, in the town of Palmer, in the county ofHampden and State of Massachusetts, have invented new and usefulImprovements in Reed-Supporting Devices for Looms, of which thefollowing is a specification.

This invention relates to improvements in the construction andarrangement of the laybeam and reed of a loom.

The object of the invention is to provide a reed which shall be asefficient as heretofore for battening, and which shall, moreover, beunusually desirable by reason of the greater elasticity or yieldingcapability of the reeddents whereby they may be free to spread, one fromthe other, opposite the edge of the race board, to permit the freepassage (and without liability of breakage) of lumpy or knotted warpyarns through the reed.

To this end the invention consists in the combination with the lay-beam,of the reed.

having its lower rib supported thereby, and supporting the dents thereofseparated from the edge of the race board of the lay-beam which rangesalong the side of the reed at a plane intermediately of the reed-ribs,and all as will hereinafter fully appear and be set forth in the claims.

In the drawings, Figure 1 is a vertical cross sectional view through thelay-beam and reed. Fig. 2 is a plan view of the same below the reed-cap.

In the drawings, A represents the lay-beam which is understood asmounted to have reciprocatory movements, as usual, and B represents thereed which comprises the usual dents and border-ribs. The lay-beam isstepformed at its rear upper portion, as seen at a, and upon the base ofthis step the lower rib of the reed is supported, being there held inplace by the clamp devices indicated by the strip, a, and bolt, :0 andthe reed-cap, b,

adjoining edge of the race-board, d. It will be here observed that theupper part of the lay-beam is to be regarded as the race-board, orracesurface, whether it be a board separately formed and attached, asindicated, or whether integrally formed with the body of the lay-beam.This race-board, or upper laybeam surface, is, in practice, to be aboutan inch and one-half, more or less, abovev the lower extremities of thereed-dents, so that the warp yarns are supported to pass through thereed at a' plane above the bottom of the reed, at which plane a verydesirable and important degree of yielding or elastic capability ispresent. As shown in Fig. 1, the edge of the race-board, d, adjoiningthe reed extends beyond the plane of the vertical wall of the lay-beambeneath it, overhanging the rear side of the lower reed-rib. In thisimproved arrangementgreat advantageis gained by the increased facilitywith which knotted or lumpy warp yarns,designedly, or accidentally soformed,may pass between the free dents of the reed and be incorporatedinto the fabric by the loom, without liability of breakage in transitthrough the reed. It

will be perceived in Fig. 1 that the vertical tion of reeds having thelower rib thereof of varying thicknesses. Fora thin rib the screws areforwardly moved to move the strip, g, against the lower rib within thegroove, while if the rib is of greater diameter or thickness the stripenters the groove farther, and all to the end of having the reed withthe battening edge of its dents always in a plane parallel to theshuttle track. This arrangement also permits the adjustment of the reedso that it may be exactly in the plane at right angles to the run of thewarp.

What I claim as my invention is' 1. In a loom, the lay-beam having adepression at its rear, a transversely adjustable strip in the verticalface of said depression engaging one side of the lower rib of the reed,

and clamping devices, substantially as described, engaging theoppositeside of said rib and securing the same to the lay-beam,

combined andoperating substantially as set forth.

2. In a loom, in combination, the reed, the lay-beam having'a depressionat itsrear, reedrib clamping devices, as a: and x securing the lower ribof the reed to the lay, and an adjustable rear bearing for said rib inthe vertical wall of said depression whereby the dents of the reed areadjusted and maintained in a position away from the edge of theraceboard of the lay, combined and operating substantially as set forth.

3.. In a loom, the step-formed lay-beam having the groove, f, the strip,g, within. said groove, one or more adjusting screws there for, thereed, and clamping devices, substantially as described, securing thelower rib of the reed to the beam, combined, and operating substantiallyas set forth.

\ i 4. Ina loom, thelay-beam havingadepression at its rear, alongitudinal bearing for the 3 lower reed-rib on the vertical face ofsaid sion at its,rear,a.longitudinal bearing for the lower reed-rib onthe vertical face of said depression, the race-board having its edge0pposite the reed-dents, projecting beyond the vertical face of saiddepression, and clamping devices, substantially as described, en-

gaging the opposite side of said rib and securing the same to. thelay-beam, combined and operating substantially as set forth.

6. In a loom, the. combination of the lay beam, the reed extending downpast the top of said beam, and means foradjusting the lower end of saidreed toward or away from the race board on the beam, substantially asdescribed.
